I am now saying that the IBM implementation is likely correct according to
"the book" and the GNU implementation is a likely "bug". But I, in a
sense, that I like the GNU error message because I, personally, think that
it will reduce typo. I.e. I think that something like:
01 A.
05 B.
10 C PIC ... .
06 NEW.
10 D PIC ... .
10 E PIC ... .
05 F.
10 G PIC ... .
05 H PIC ... .
is going to confuse the <elided> out of someone. Not all of the "10" levels
under B are at the same nesting level. It just seems "weird" that the 10 C
and 06 NEW are at the same nesting level. IMO, the "NEW" should be at level
10 and the D & E should be changed to, say, 15. But someone _could_ just
insert the NEW as above so as to "minimize the number of lines changed" (06
NEW was an after thought to group D & E). It just confusing __TO ME__.
Maybe it is just fine to a COBOL guru.
